The connecting member is internally provided with a chamber communicating with the inside of the telescopic suction cup, and the chamber is provided with a bead body which can be displaced up and down by vacuum suction. When assembling, the connecting member is sleeved on the outer side of the inlet end of the vacuum suction tube of the suction device, so that the vacuum suction tube communicates with the chamber, so that the suction device can contact the plate through the telescopic suction cup (for example: printed circuit On the board, the flexible circuit board, the wafer, the panel or the glass substrate, etc., the vacuum suction tube is further activated to perform the suction operation on the telescopic suction cup to adsorb the plate to the bottom of the telescopic suction cup, and the bead is displaced by the vacuum suction. Blocking the air inlet of the vacuum suction tube to prevent the outside air from flowing into the vacuum suction tube and breaking the vacuum. However, the vacuum suction tube generally used in the suction device has a plurality of different sizes. Therefore, when the suction cup assembly of the above structure is installed, It is easy to seal the vacuum suction tube because the beads and the air inlet are not in the same size, so that the outside air can easily enter the vacuum suction tube. Creating a vacuum suction pipe failure due to breaking vacuum.

Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.

The main purpose of the present invention is to utilize the adjustment ring and the bead body disposed in the chamber of the connecting member to be displaced by the vacuum suction during use, so that the gas passage between the vacuum suction tube and the chamber is adjusted by the adjusting ring. After adjustment, it is blocked by the bead seal. When the suction cup assembly is applied to vacuum suction tubes of various sizes, it can effectively prevent outside air from flowing into the vacuum suction tube, avoiding vacuum failure of the vacuum suction tube, and achieving convenient use. effect.

In order to achieve the above object, the suction cup assembly of the present invention is connected with a vacuum suction tube for inhaling and releasing air to the suction cup assembly, and includes a telescopic suction cup and a connecting member, and a passage for gas circulation is penetrated in the telescopic suction cup. The connecting member is internally provided with a chamber, and the top of the chamber is provided with an opening for the end of the inlet of the vacuum suction tube to enter into communication with the chamber, and the bottom is provided with a main venting hole communicating with the passage of the telescopic suction cup, and the cavity The contents of the chamber are provided with a bead body and an adjustment ring. The bead body and the adjustment ring system are driven up and down by the vacuum suction generated by the vacuum suction tube, and the adjustment ring is interposed between the bead body and the opening, and is provided with an adjustment hole. When the telescopic suction cup contacts the plate and the vacuum suction tube is activated to perform the suction operation on the connecting member, the adjusting ring is driven by the vacuum suction force toward the opening, and the path cross-sectional area between the gas circulation chamber and the vacuum suction tube is adjusted by the adjusting hole thereof. And the bead body is closely attached to the adjusting hole by vacuum suction to seal the adjusted gas circulation path to prevent outside air from flowing into the vacuum suction tube .

In the aforementioned suction cup assembly, the aperture of the main venting hole of the connecting member is smaller than the outer diameter of the bead to prevent the bead from falling out of the cavity.

In the above-mentioned suction cup assembly, the peripheral end of the main vent hole of the connecting member is provided with a side vent hole, and the side vent hole communicates with the passage of the chamber and the telescopic suction cup.

In the above-mentioned suction cup assembly, the connecting member has a plurality of side vent holes, and the plurality of side vent holes are spaced apart from the periphery of the main vent hole, and each side vent hole communicates with the passage of the chamber and the telescopic suction cup.

Referring to the first and second figures, it can be clearly seen from the figure that the suction cup assembly of the present invention comprises a telescopic suction cup 1 and a connecting member 2, wherein:

A passage 11 through which the gas flows is inserted through the telescopic chuck 1.

The connecting member 2 is connected to the telescopic chuck 1 and has a chamber 1 disposed therein, and a bead body 22 and an adjusting ring 23 are disposed in the chamber 1. The top of the chamber 1 is provided with an opening 211, and the bottom portion is provided with The main vent hole 212 of the channel 11 of the telescopic suction cup 1 is connected to the main vent hole 212. The aperture of the main vent hole 212 is smaller than the outer diameter of the bead body 22 to prevent the bead body 22 from falling out of the chamber 11, and the main vent hole 212 is spaced apart from the periphery. The plurality of side vents 213, each of the venting holes 213 are connected to the chamber 1 and the passage 11 of the bellows 1, and the aperture is smaller than the aperture of the main venting hole 212. The beads 22 and the adjusting ring 23 are driven by vacuum suction. Displacement, and the adjustment ring 23 is located between the bead 22 and the opening 211, and is provided with an adjustment hole 231.

Please refer to the second figure. As can be clearly seen from the figure, when the present invention is used, the connecting member 2 is sleeved on the outer side of the end of the air inlet 32 of the vacuum suction tube 3, so that the vacuum suction tube 3 advances. The end of the gas port 32 passes through the opening 211 of the connecting member 2, and is located in the upper half space of the chamber 1, allowing the gas passage 31 in the vacuum suction pipe 3 to communicate with the chamber 1, and the adjusting ring 23 is located at the bead body. 22 between the end of the air inlet 32 of the vacuum suction tube 3, and then, the telescopic suction cup 1 can be contacted with the plate (not shown), and the vacuum suction tube 3 is opened to the chamber 1 of the connecting member 2. The suction operation is performed to adsorb the plate to the bottom of the telescopic suction cup 1, and the adjustment ring 23 is driven by the vacuum suction toward the opening 211 and abuts against the end of the air inlet 32 of the vacuum suction tube 3 to adjust The aperture of the hole 231 adjusts the path cross-sectional area between the gas flow chamber 1 and the vacuum suction tube 3. The bead body 22 is driven by the vacuum suction to abut against the bottom of the adjustment ring 23, and closely fits the adjustment hole 231 to block The adjusted gas circulation path allows the suction cup assembly to be applied to various vacuum suction tubes 3 of different sizes. Effectively prevent the outside air flowing into the vacuum suction tube 3, to avoid the vacuum suction pipe 3 vacuum break failure to achieve the effect of convenience.

Please refer to the third figure. It can be clearly seen from the figure that when the suction cup assembly with the plate (not shown) needs to release the plate, it is only necessary to activate the vacuum suction pipe 3 to release the suction cup assembly and let the gas The air inlet 32 of the vacuum suction tube 3 flows into the chamber 1 of the connecting member 2, so that the bead body 22 falls to the bottom of the chamber 1 and abuts against the main venting hole 212, and the adjusting ring 23 falls to the bead. In the upper half of the body 22, at this time, the gas can flow into the chamber 1 through the gas passage 211, and flow into the passage 11 of the telescopic chuck 1 via the side vent 213, and adjust the pressure value in the passage 11 to quickly release the sheet.
